Description
Technical field
The invention belongs to counting passenger flow of buses fields.
Background technology
Gradually accelerate with the paces of urban construction, demand of the citizen to traffic trip is growing, and traffic congestion is made
Problem to restrict urban development has obtained people and has more paid attention to.Various regions government launched respectively relevant policies support in recent years
The development of public transport.The research emphasis of public transport is the scheduling problem of public transit vehicle, and passenger flow data is public bus network tune
The basis of solution formulation is spent, full and accurate effective passenger flow data is not only the premise of operation plan formulation, and runs through scheduling strategy system
Determine whole process.
Bus passenger flow data statistical approach can be divided mainly into two classes at present：One kind is manual counts, and this method is
The main method of many city bus volume of the flow of passengers investigation in China, the defect of this method are that survey mode is single, if necessary
It carries out this method of long-term passenger flow investigation to be obviously not suitable for, can not unite to a large amount of data because human resources are limited
Meter investigation, and the accuracy of data have it is to be tested；Another kind of is relatively advanced passenger flow information acquisition method, such methods
Include mainly bus IC card information bank statistic law and automatic counter system, the defect of bus IC card information bank statistic law is meeting
There is the card using information mistake of passenger and influence data accuracy, automatic counter system is mainly that pressure sensor counts at present
Device, photosensitive sensor counting device, passenger's counting etc. based on image detection, pressure sensor and photosensitive sensor lack
Point is that not easy to install, cost is high, precision is low and maintenance cost is higher, the defect of passenger's method of counting based on image detection
It is easily to be affected by the external environment, and processing speed is slow when carrying out multiple target tracking, precision can not ensure when passenger is more.
